	 * PHQL is implemented as a parser (written in C) that translates syntax in
	 * that of the target RDBMS. It allows Phalcon to offer a unified SQL language to
	 * the developer, while internally doing all the work of translating PHQL
	 * instructions to the most optimal SQL instructions depending on the
	 * RDBMS type associated with a model.
	 *
	 * To achieve the highest performance possible, we wrote a parser that uses
	 * the same technology as SQLite. This technology provides a small in-memory
	 * parser with a very low memory footprint that is also thread-safe.
	 *
	 * <code>
	 * $intermediate = Phalcon\Mvc\Model\Query\Lang::parsePHQL("SELECT r.* FROM Robots r LIMIT 10");
	 * </code>
